摘要
质子交换膜燃料电池双极板上流场的设计在很大程度上影响燃料电池的性能.传统燃料电池平行流场虽然结构简单,易于加工,但存在气体分布均匀性不佳,水淹现象严重等问题.本文对传统的平行流场进行改进,设计了一种新型混合流场的质子交换膜燃料电池,并利用Comsol软件对新型混合流场燃料电池的阴极气体浓度、水的摩尔浓度、电流密度进行计算分析.结果表明,混合流场燃料电池在气体分布均匀性、水的去除能力上均优于传统平行流场燃料电池.
The design of flow field on the bipolar plate of proton exchange membrane fuel cell greatly affects the performance of the fuel cell.Although the traditional parallel flow field is simple in structure and easy to process,there are some problems such as poor uniformity of gas distribution and serious flooding.In this paper,the traditional parallel flow field is improved and a new proton exchange membrane fuel cell with mixed flow field is designed.The concentration of cathode gas,molar concentration of water and current density of fuel cell with new mixed flow field are calculated and analyzed by Comsol.The results show that the fuel cell with mixed flow field is superior to the fuel cell with parallel flow field in gas distribution uniformity and water removal ability.
